NITED STATES GEORGE PAUL SCHUSTER, OF ST. LOUIS, MISSOURI, ASSIGNOB TO THE CRESCENT MANUFACTURING COMPANY, OF SAME PLACE.

BARB-WIRE MACHINE.

SPECIFICATION forming part of Letters Patent No. 322,981, dated July 28, 1885.

Application filed December 8, 1884.

To all whom it may concern:

Be it known that I, GEORGE PAUL SCHUSTER, of St. Louis, Missouri, have made a new and useful Improvement in Barb-Wire Machines, of which the following is a full, clear, and ex act description.

The invention is an improved mechanism for applying the barbs to the strand-wires in that type of barb-wire machines wherein the strandavires are fed longitudinally through and the barb wire or wires across the delivery end of a head which rotates on its longitudinal axis, and also has a reciprocating longitudinal movement in the machine.

By means of the improvement the barbs can be applied more rapidly and thoroughly to the strand-wires. It consists as follows: 111 place of the customary pair of barb-formers adapted to close and open in a reciprocating manner across the delivery end of the rotating head, a tube is arranged in line with and in opposition to the rotating head, but far enough removed therefrom to provide room for the barb wires to cross between the strand-wires, and for the barb-severing devices to operate in the customary manner.

The tube is connected with the rotating head,

so that it shall keep with the rotating head in its reciprocating longitudinal movement in the machine; but it is also so held and operated as to have a reciprocating rotary movement on its longitudinal axis in the opposite direction to that of the rotating head in the forward movement of the head and tube in the machine. The tube at its end toward the rotating head is furnished with projections,which, during the rotation-of the tube in its forward movement, act not only as shoulders for the projecting barb-wire ends to bear against, but also, by reason of the rotation of the tube in the opposite direction to that of the rotating head, to wrap the barb-wire ends upon the strand-wires. The tube is also sufficiently large in its internal diameter to enable the completed barb-wire to be fed through it.

The annexed drawings, making part of this specification, illustrate the improved mechanism. Only that portion of the machine is exhibited that is immediately connected with the improvement in question, the remaining (No model.)

crosssection on the line 7 7 of Fig. 4, and

Fig. 6 illustrates the action of the tube-projections upon the barb-wires.

The same letters of reference denote the same parts.

A represents the rotating head. It rotates in the bearing a in the direction indicated by the arrow (6, Figs. 2 and 4. The strand-wires B B are fed through the perforations b bin the head, and -the barb-Wires C C are fed, in the present instance, through the bent tubes 0 0 upon or in the head. The bearing a is attached to and is supported by the slide D, which in turn is moved reciprocatingly upon the bed-plate E, as indicated by the positions shown, respectively, in Figs. 2 and 4.

F F represent the barbsevering knives. They are attached to the arms f f, which are adapted to be rocked on the bearings f f. All of the parts thus far mentioned are made and worked in the usual manner.

, G represents the tube used in forming the barbs. Its bearing g, in which it rotates reciprocatingly, is supported by and is attached to the slide D. The tube is held in the hearing longitudinally, so that it shall follow the slide in its movement upon the bed-plate. The tube is extended beyond the bearing 9, and in the extension 9 are the spirally-extended grooves Figs. 2, 4, 7. The object of the grooved extension is to provide for the reciprocal rotation of the tube. To that end the grooved extension is operated in connection with the fixed pins H H, Fig. 7. These pins are held in some fixed part of the machine, and so that their inner ends shall respectively engage in the grooves gtgfland thereby cause the tube to rotate as it,with the slide, is moved longitudinally in th.e machine. The

preferable means for supporting the pins is the circular frame I, which encircles the tubeextension and is upheld by the arms z t, which in turn are attached to the bed-plate or some other stationary part of the machine 7 suitable therefor.

jections g 9 As the head A is withdrawn, the barbwires are fed between the head A and the tube G and into the plane of the tube-pro- These tube-projections are the means immediately employed in wrapping the barb-wires upon the strand-wires. They project from the tube, at opposite sides thereof, toward the head A, and they are preferably in the form of round pins. During the backward movement of the head A the pins do not act upon the barb-wires, for during such backward movement the pins H H act to cause the tube G to rotate in its bearing 9 in the same direction with the head A, as indicated by the arrow 9, Fig. 4:; but when the head and tube are moved forward, as in Fig. 2, the pins H H act to cause the tube to rotate in the opposite direction to that in which the head is rotating, as indicated by the arrow 1 Fig. 2, and the pins g g, in consequence, are moved against the barb-wires, and the barb wires are thereby carried around the strand-wires, respectively.

The strand-wires lead from the head A through thetube G, and the finished barbed wire passes through the tube and onto the customary spool, for when the barbs have been wrapped upon the strand-Wires they are sufficiently shortened for the strand-wires carrying them to enter and pass through the tube.

The tube G, having the projections g gfland adapted to be moved in the manner described, is useful as a means for forming the barbs upon the strand-wires irrespective of the rotary movement of the head A. It is especially useful, however, in connection with a head adapted to be rotated in the manner described; for, by reason of the head and tube rotating in opposite directions during the formation of the barbs, the barbs can be formed more rapidly than hitherto'has been practicable. Further, the barbs are wrapped farther around upon the strands, and the strands in consequence do not need to be so closely twisted as hitherto has been necessary.

The projections 9 .9 as well as the tube G, may be constructed, and the tube may be held in the position described and rotated for the purpose set forth, in any desirable manner and by any desirable means consistent with the end in Viewnamely, the carrying of the projections g 9 around the strand-wires so as to enwrap the barb-wires thereon.

The tube, as shown, has a bushing, 9 and the projections g g are held between the two parts. This enables the various parts of the tube to be readily replaced when worn.

When but a single barb-wire is used, but a single thread, F, and a single projection, g, are needed, and in such case, and by suitably extending the grooves g g,the tube can be rotated farther around at each stroke, and the barb thereby wrapped farther around upon the strand-wires.

I am aware that a wire-barbing machine having two fliers rotating continuously in opposite directions, one of said fliers having a head which rotates with and has a longitudiw nally-reciprocating movement in the flier,and carrying a cutter, and the other of said fliers having a barb-former which has a longitudinally-reciprocating movement in the flier and rotates interrnittingly with the flier, has heretofore been designed.

I claim-- 1. A barbwire machine having a tube provided with one or more projections, g g, and having a reciprocating rotary movement, substantially as and for the purpose set forth.

2. The combination,in a barb-wire machine, of the head A, the slide D, the bed-plate E, the tube G, having the grooves g and projections 9, the frame I, and the pins H H, substantially as described.

3. The combination, in a barb-wire machine, of the rotating head A and the reciprocating rotating tubeG, having the projections 9, substantially as described.

4..- The combination,in a barb-wire machine, of the rotating head A, the knives F F, and the reciprocating rotating tube G, having the projections substantially as described.

5. The combination, as described, of the head A, perforated at b b, and having the tubes or passages c 0, with the slide D, the bed-plate E, the knives F F, the tube G, having the grooves g g and projections i g, the pins H H, and the frame I.

Witness my hand this 29th of November, 1884.

GEORGE PAUL SOHUSTER.
